To all whomc't may concern:

`Be it known that I, STOYAN K. RADKOFF, a. citizen of the United States, residing at Detroit, county of Vayne, State ofzMichigan, have invented a certain new and useful Improvement in Window-Display and Advertising Devices, and declare the following to be a full, clear, and exact description of the. same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the acn companying drawings, which form a3 part of this specification. i

My invention relates to advertising devices and more particularly to means for displaying and advertising automobile tires,-as shown in the accompanying drawings and more particularly described in the following specification and claims.

One of the objects of my invention is to provide a device adapted to support and rotate a tire mounted on a rim carrying spokes, from the hub of which project oscillating arms,-representing wings-actuated by a motor which also drives the mechanism employed to rotate the,l tire.

Another object is to provide a device in which the tread of the tire rests upon the means employed to rotate it, the driving mechanism being concealed in a suitable case adapted to rest upon the floor of a showwindow front, or other like support.

With the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination of parts and details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment herein shown without departing from the spirit of my invention.

In the drawings accompanying this specification: V

Figure l is a cross-sectional view through the device, with parts in elevation.

Fig. 2 is a longitudinal sectional view through the device, showing a fragmentary portion of a tire and rim in position, to indicate its operation.`

Fig. 3 is a similar longitudinal sectional view of the device as viewed from its opposite side.

Referring now to the letters of reference placed upon the drawings A, denotes an automobile or like tire casing.

B, indicates the rim on which the tire is mounted.

C, designates the spokes of a wheel, D, its hub portion. E, denotes a casing adapted to rest upon a floor like support in which is housed an `electric inotorF, having its armature shaft I4", extending in opposite directions and j ournaled in the frame G.

H, isa driving pinion carried by the shaft in mesh with the intermediate gear H', in turn meshing with a gear H2, on the shaft I, also journaledin the frame G. J, denotes a driving. drum carried by the shaft I, on whichthe tire A, rests and by means of which it is rotated. J', is an idler drum j ournaled in a suitable supporting frame K, *andfserves to assist in supporting the tire.

L, denotes a bevel gear carried by the armature shaft on the opposite side of the motor, in mesh with a bevel gear Mg-the shaft M', of which is also journaled in the frame N, indicates a universal joint connection between the shaft M', and a shaft N', which extends upwardly through the hub portion D, where it is fitted with a vniiter gear O, in mesh with a like gear O', carried by a shaft O2, journaled in the faceplates D, of the hub portion. P, denotes a tube in which the shaft N', is sleeved, eX- tending from a boss carried by one of the face plates D', to a hub E', in the casing .E g-with which it is pivotally connected by screws e, c, projecting through the wall of the-hub. P', is a tube extending from the opposite face-plate D', to the casing li), with which it is pivoted by means of the transw verse pin 79, carried by the lugs 2J', rising from the wall of the casing. The tubes P, and P', assist in supporting the hub portion with the parts contained therein and operate in conjunction therewith.

Mounted on the shaft @ZV-within the hub portion,--is an eccentric Odg-WQ', is its strap, and Q?, a reciprocating rod connected therewith and traveling in a guide D2, carried by one of the face plates D.

R, R, denote rocker arms projecting through openings in the face-plates and pivoted at R', thereto :Mthe ends of the arms being slotted to receive a transverse pin R2, carried by the reciprocating rod Q2.

Having indicated the several parts by reference letters, the operation of the device will be readily understood.

yThe projecting end of the rocker arms R, R, are fashioned to represent wings and upon the motor being energizeds the rocker arms are actuated through the eccentric,

and bevel gearing, driven bytliemoto'r, in4

semblance of a Winged flight ;-While the Wheel or tire is rotatedbythe driving drum" J, upon which `it rests, thereby producing a very. novel and pleasing result and serving" invention frame, adapted to support and rotate ay Wheel, a motor, means actuated by the motor to operate the driving drum', rocking arms pivoted in the frame adjacent to the hub portion ci the wheel, and means driven' by said motor adaptedv to actuate said rocking arms.

, In a` device of the character described, a frame, a motor supported by the frame, a drum actuated by the motor adaptedto' support and` rotate a' Wheel, the Wheely endV .plates in line with Ithe hub portion of the Wheel, adjustable standards for supporting Within' the' case, a Wheel driving drum journaled in the frame, a train of gears actuated by the motor for operating the drum, an idler dru'm,a Wheely supported onI said'- drums and rotated bythe driving drum, plates in line withI the hubv portion of the Wheel, standards pivoted to'the case for supporting said plates, rocking. arms pivoted tothe plates, andzsuitable gearing driven by the motor for actuating said rocl'ing arms.l`

In' testimony \'vhereof` I sign thisv specificationin the presence of tW-o witnesses. STOYA K. RADKOFF. itnessest S. E. THOMAS, N; VHURLIW.l
